I present the first documented record of the Belted Kingfisher, Megaceryle alcyon, in mainland Ecuador. A young male M. alcyon was observed and photographed in the surroundings of Puerto López, province of Manabí, Ecuador in September 2005. A very rare boreal vagrant in mainland Ecuador, M. alcyon was previously known from a single sighting in December 1992 and was a hypothetical species pending corroborating evidence, which is now provided.
